2000 Enggano earthquake

Indonesia is well known for strong earthquakes: the 2000 Enggano event marked the beginning of an ongoing period of seismic activity in the area, highlighted by the 2004 Indian Ocean earthquake. The 2000 Enggano earthquake took place at the southeastern end of the fault segment that ruptured during the 1833 Sumatra earthquake. This group of earthquakes, in addition to the 2005 Nias–Simeulue earthquake, all ruptured along the megathrust that forms the interface between the Australian and Sunda plates. This event was the only one not to cause a damaging tsunami. ==Earthquake==

The earthquake involved the rupture of two different faults with different mechanisms. The first subevent ruptured a north–south striking fault within the Australian plate with a left lateral strike-slip mechanism. The earthquake rupture propagated northwards until it reached the megathrust, triggering the second subevent along the Sunda megathrust itself. The strike-slip rupture probably represents slip on a pre-existing fracture zone, similar to the likely cause of the M 7.9 earthquake that struck about 1,000 km to the south on 18 June 2000 with a similar mechanism. ==Damage and casualties==

According to the USGS' PAGER-CAT catalog, the earthquake killed 103 people and injured up to 2,585 others, however the International Federation of Red Cross and Red Crescent Societies reported 141 deaths. At least 85 people were killed, 2,185 were injured, 354 houses were destroyed and 669 others were damaged in mainland Bengkulu, with 43 deaths in North Bengkulu, 39 in South Bengkulu Regency and three in Central Bengkulu. All concrete structures collapsed and most wooden structures were severely damaged there. In the village worst struck, several hundred structures were reported in ruins. ==Aftermath and response==

International relief teams arrived in the region within several days. Relief efforts were impeded by fallen telephone poles, which blocked the supplies. The main problem found in the affected areas was a lack of water supply and electricity, these facilities having been cut off by oscillation. He called for a rapid international response to the quake, and said he would keep its victims in his prayers. Students from the University of Bengkulu traveled in Red Cross teams consisting of seven people, pulling victims out of the rubble and taking them to first aid posts staffed by their colleagues, while politician Mar'ie Muhammad spent three days in Bengkulu, visiting affected areas and organizing the continuation of the relief operation with local authorities. Volunteers helped donate 1,000 of a total of 15,000 family kits containing cooking utensils, sarongs, sleeping mats, plastic sheeting and hygienic items. Over 400 of the kits were loaded onto a boat and 40 volunteers and the International Federation relief delegate traveled to Enggano Island to carry out the first distribution. ==Wharton Basin event==

}} Two weeks later on June 18, another 7.9 event occurred about to the southwest in the Wharton Basin. At the time, it was the largest intraplate earthquake in the Indian Ocean until the 2012 Indian Ocean earthquakes. The earthquake knocked items from shelves and triggered a tsunami at the Cocos (Keeling) Islands, near the epicenter. ==See also==
